Dimitris Tzionas

Dimitris Tzionas is an Assistant Professor for 3D Computer Vision at the University of Amsterdam (UvA), leading research in the intersection of Computer Vision, Computer Graphics, and Machine Learning. His work focuses on modeling human-object interactions, 3D/4D perception, and synthesis for applications in Ambient Intelligence, Virtual Assistants, and the Metaverse. He holds an ERC Starting Grant (€1.5M) and ELLIS Amsterdam affiliations.

Previously, he was a Research Scientist at Max Planck Institute for Intelligent Systems (MPI-IS), contributing to projects like the GRAB dataset and MANO/SMPL body models. He earned his PhD from the University of Bonn on hand-object interaction, advised by Jürgen Gall, and completed his MSc at Aristotle University of Thessaloniki in Electrical & Computer Engineering.

His research has produced impactful datasets (e.g., GRAB, InterCap, DAMON) and methods like InteractVLM and PICO, advancing human-centric AI. He actively serves on CVPR/ICCV/ECCV committees and teaches 'Introduction to Computer Vision' at UvA. Notable awards include NVIDIA grants, Google Research Gifts, and multiple Outstanding Reviewer recognitions.

His lab collaborates widely, advising over 10 PhD/MSc students and postdocs, with projects funded by ERC, ELLIS, and industry partners like NVIDIA and Google. Key themes include 3D reconstruction, interaction modeling, and generative AI for realistic avatar creation.
